Dental implant surface technology has evolved from a relatively smooth machined implant surface for osseointegration to more roughened osteoconductive surfaces. Recent studies suggest that peri-implant soft tissue inflammation with progressive bone loss (ie peri-implantitis) is becoming a prevalent condition. One possibility that could explain sucha a finding is that more bacterial plaque forms on the roughened implant and abutment surfaces, which may result in the peri-implant inflammation if the soft tissues. This study compared 36 tissue-level implants with a machined transmucosal collar to 36 implants with a relatively roughened transmucosal surface in the dog. The results demonstrated that the connective tissue contact was similar between the two implant types but that the junctional epithelium and biologic width dimensions were greater around the implants with the machined collars...

Guidelines for the Diagnosis and Treatment of Peri-Implant DiseaseAlthough some risk factors of peri-implant disease are well defined, the lack of efficient and predictable approaches to treat peri-implantitis has created difficulty in the management of those complications. The aim of this review was the evaluate the reliability of the diagnosis methods and to provide a set of guidelines to treat peri-implant disease. A search of PubMed and a hand search of articles related to peri-implant diseases were conducted up to August 2013. A summary of the current methods for the diagnosis of peri-implantitis, its potential risk factors, and a flow chart to guide the clinical management of these conditions are presented.

Fibrin Assisted Soft Tissue Promotion (FASTP) - A New Perspective in Periodontal Plastic SurgerySoft tissue recession around teeth and implants is an epidemic problem in the field of dentistry. A predictable and long-term soft tissue augmentation outcome is primarily dependent on proper diagnosis, prognosis and treatment planning. Harvesting limitations of autogenous tissue from the palate represent a true challenge when treating patients with multiple recessions or gingival deformities around teeth and dental implants. The Advanced Platelet Rich Fibrin (APRF) and injectable platelet-rich fibrin (iPRF) are promising tissue promoters that can be a suitable alternative option.

Surgical Veneer Grafting: Utilization in Immediate Implant PlacementThe management of the digital implant prosthetic dentistry, especially in the anterior esthetic area, is one of the hottest topics in Dentistry. The diagnostic phase is critical. In the course, are discussed all the parameters to achieve the correct diagnosis of the socket and the various treatment plan correlated to each anatomical type of socket. The Dual Zone approach (bone zone and tissue zone) will be evaluated and discussed in detail, regarding each of their variables.

Hard and Soft Tissue Augmentation: Optimizing Esthetic Results for the Restorative DentistContemporary patient expectations have made esthetics a major requisite of all treatment plans, especially in situations where there is a high smile line. Although new restorative materials have highly improved predictability and esthetic outcomes, soft and hard tissue management play a fundamental role when working in esthetic areas. To achieve ideal esthetics, preservation of the natural soft and hard tissue architecture is a primary clinical objective. These new proposed techniques illustrate the importance of pre-prosthetic soft and hard tissue management when working in highly esthetic compromised areas.

Peri-Implantitis: Diagnosis, Etiology and TreatmentThe dental implant therapy has evolved both in implant surface and design. The reason for the initial crestal bone loss has been proven and the risks of having a peri-implantitis have increased due to the early exposure of roughened surface. The prevalence of peri-implantitis is at a range of 28 to 56%.
The role of dental professionals nowadays is to know how to interpret the signs of inflammation and establish the diagnosis of peri-implantitis, which is the most challenging, and be able to treat it properly since this is becoming a more needed therapy.

Connective Tissue Graft Harvesting Techniques - Part 1In this presentation, Prof. Giovanni Zucchelli develops a critical comparison between the different CTG harvesting techniques, and shows the correct management of this kind of graft as well as its use in coronally advanced flap surgical technique for the treatment of gingival recessions.
